Vedclass · Answer

(B) The reaction involves the acid-catalyzed ring opening of a cyclic ether (dihydrobenzofuran derivative).$1$. Protonation of the ether oxygen $(^{18}O)$ occurs first.$2$. The bond between the oxygen and the more substituted carbon (the benzylic carbon) breaks to form a stable carbocation intermediate (stabilized by the benzene ring).$3$. Water attacks the carbocation,followed by deprotonation to form the alcohol.$4$. The $^{18}O$ atom remains attached to the carbon that was part of the ring,which becomes the hydroxyl group in the final product.Therefore,the product is $2-$($2$-hydroxyethyl)phenol where the $^{18}O$ is part of the $-OH$ group.

$C$. $CH_{3}CH_{2}OH \rightarrow H_{3}C-CH(OH)-CH_{3}$	$III$. $(i)$ $CH_{3}OH, H^{+}$; (ii) $H_{2}$,Catalyst
$D$. Benzene $\rightarrow$ Phenol	$IV$. $(i)$ conc. $H_{2}SO_{4}, \Delta$; (ii) $H^{+}/H_{2}O$
